Thanks! I wasn't aware of such documented lifecycle highway key, I will use it for now with fixme=survey.

Hi Michael,

No worries at all — we’ve all made that mistake at some point. I’ve reverted your initial change.

When upgrading tags on a trail you've surveyed, it’s best to drag and drop the GPX traces directly on the map and split the path or road segments at the points where you turned back or changed direction. That way, you can safely apply tags only to the sections you've actually surveyed.

Also, iD has a feature to highlight changes, which helps visualize the edits you're making.

Best,
Julien

Hi Michael,

Did you survey the entire trail here? The trace looks like it might come from an enduro race, so I’m a bit skeptical that it was fully walked. If you only surveyed a portion of it, the segment should be split and the tags updated accordingly.

Let me know—I'll adjust things as needed. And if you have any questions about the hiking guide, feel free to ask.

Best,
Julien

Hi Michael, hope you're doing well.

Was this change based on a personal survey?

Just a heads-up: access tags like `bicycle=no` or `horse=no` should only be used if there are actual signs prohibiting access—not to describe how practical or suitable the path is. As far as I know, there are no legal restrictions here, so I’ll need to remove those access tags.

If you’ve personally surveyed the route on foot, horse or by mountain bike, it’s recommended to indicate suitability using `sac_scale`, `mtb:scale` or `horse_scale` instead.

ฉันสังเกตว่าการแก้ไขล่าสุดของคุณได้ลบถนนสำคัญหลายจุด รวมถึงสะพานบนทางหลวงหลัก ดังนั้นฉันจึงย้อนการแก้ไขกลับเพื่อป้องกันปัญหา หากเป็นข้อผิดพลาด ฉันยินดีช่วยแนะนำวิธีแก้ไขที่ถูกต้อง แจ้งให้ฉันทราบหากคุณมีคำถามใด ๆ!

I noticed your recent edit removed key road segments, including a major highway bridge, so I’ve reverted it to prevent issues. If this was unintentional, I’d be happy to help guide you on editing correctly. Let me know if you have any questions!

Thanks a lot for your contributions! Just a friendly tip: try to keep your changes smaller, like focusing on one country at a time.

Hi Ropino, thanks for your contributions! Based on your profile, I assume this change wasn't based on a ground survey? Just a heads-up—`highway=road` can be used for segments that haven't been confirmed with local knowledge (e.g., mapped from imagery alone). This tag can represent anything from a narrow footpath to a motorway and is generally ignored by routers, so connectivity shouldn't be a concern.

สวัสดี Peetang618,
ขอบคุณมากสำหรับการมีส่วนร่วมของคุณ! อยากจะแบ่งปันเคล็ดลับเล็กๆ น้อยๆ นะครับ สำหรับถนนที่อยู่อาศัยแคบ ๆ ตามคำแนะนำใน Wiki ล่าสุดของประเทศไทย ให้ใช้ highway=residential พร้อมกับ lanes=1 วิธีนี้ช่วยให้ข้อมูลมีความสอดคล้องและทำให้ทุกคนเข้าใจลักษณะของถนนได้ง่ายขึ้น ผมได้ปรับปรุง changesets ของคุณให้ตรงตามข้อแนะนำนี้แล้ว
ถ้าคุณมีคำถามหรือข้อเสนอแนะเพิ่มเติมเกี่ยวกับเรื่องนี้ โปรดแจ้งให้ผมทราบได้เลยนะครับ!
ด้วยความปรารถนาดี,
Julien

Hi Peetang618,
Thanks so much for your contributions! I just wanted to share a quick tip: for narrow residential roads, the latest Thailand wiki recommends using highway=residential with lanes=1. This helps ensure consistency and makes it easier for everyone to understand the road’s characteristics. I've updated your changesets accordingly.
If you have any questions or thoughts about this, feel free to let me know!
Best,
Julien

Hi EZ_TT, thanks for your contributions! I reverted the roundabout classification change in two of your changesets. Roundabouts should generally match the highest road type they connect. Let me know if there was a reason for the change. Best, Julien

@Aleksandar Matejevic: user joined OSM and made conflicting major highway classification changes in Thailand. Local mappers have already reverted all edits. You should consider doing the same. Best, Julien

Dear แดนสรวง วงศ์สรรคกร, Your recent edits changed major highway classifications, which can disrupt routing. Most have been reverted. Please start with smaller local improvements and discuss major changes with the community first. Best, Julien

Your recent changes to highway classifications conflict with the existing data and don't align with Thailand OSM guidelines. Please review the highway classification before making such edits. In the future, it’s important to ensure changes are consistent with the community standards.

Hi Michael, that sounds great! I’m based in Chiang Mai, though I’m more into off-road motorcycling than hiking. I’ve been improving and maintaining OpenStreetMap in Chiang Mai for the past four years and regularly contribute to mapping tools and wikis for Thailand and beyond.

You might find this hiking guide helpful for mapping in Thailand—it includes useful links to local hiking and OpenStreetMap communities:
[WikiProject Thailand/Hiking Guide](osm.wiki/WikiProject_Thailand/Hiking_Guide)

Visual examples will be added in the near future.
Happy hiking and mapping!

Hi Michael,

Thanks for your contributions! You may have noticed that I updated the highway classification and permissions. Are you familiar with OpenStreetMap tagging conventions? Permissions are typically based on signage and legal aspects rather than physical characteristics.

If you'd like to recommend this track for walking, consider using `sac_scale=strolling` or `sac_scale=hiking`.

You can find more details here:
🔗 [Highway Tagging](osm.wiki/Key:highway)
🔗 [SAC Scale](osm.wiki/Key:sac_scale)
🔗 [OSM Thailand Project](osm.wiki/WikiProject_Thailand)

Let me know if you have any questions!

Cheers,
Julien

Cool. You're not alone, and I haven’t been mapping as long as you :D There’s always something new to learn and ways to improve, and OSM is great for that.

Hey Paul, thanks for reaching out own this topic!

The main reason these tag combination exists is to educate local mappers to use the appropriate scale tag instead of legal access tags which were heavily abused locally.
While using bicycle/foot/motorcycle/horse=yes can be technically correct if the way is legal and accessible, it has no effect in Thailand since paths/tracks are by default legally accessible to all kind of vehicles.
Such scheme led people using `bicycle/foot/motorcycle/horse=no` values on difficult/impossible ways which has been a subjective and conflicting matter.

Also I believe some values is better than none because in Thailand many paths/tracks were added from unknown source (imagery/import) and sometimes do not exist, so having some info when we know someone use a path on mtb is better than none.

But I am with you that these undocumented tags may cause issues with software maintenance (StreetComplete?), so a few options are possible:
- Remove them but we loose some info on whether those ways were feasible with a certain vehicles (hence exists)
- Convert them back to legal access tags (motor_vehicle/motorcycle/foot/horse=yes) and find another way to educate mappers
- Move them to a prefix tag like `fixme:smoothness=unknown` or similar.

Your thoughts ?

Best,
Julien

Hi cdohrmann,
Thanks for your contributions!

Just a heads-up—please don’t downgrade unclassified/tertiary roads to highway=track just because they’re unpaved. Road classification is based on function, not surface, so it's best to use tags like tracktype=grade2, surface=compacted/gravel, and smoothness=bad/very_bad instead.
If your map renderer doesn’t support these, you might find GaiaGPS and other apps more useful.

Also maxspeed should only be used for legal speed limits, not practical ones. If you really want, you can use maxspeed:practical, but it’s not recommended since it’s pretty subjective.

I’ve been working to keep tagging consistent in Northern Thailand, so I’ll need to go through and fix these changes manually. Would appreciate your help in keeping things aligned—let me know if you have any questions! Best, Julien

Hi Dave,

This is an old topic, but I wanted to check—do you typically use *maxspeed* for actual legal limits or practical considerations? I've noticed some mappers applying *maxspeed* heavily for practical reasons, but this should either go under *maxspeed:practical* or be removed altogether since it's too subjective.

Cheers,
Julien

Hi Dave, feel free to remove. Those ways that are clearly visible from imagery but were added without local knowledge, I tag them now as highway=road. Cheers, For more info: https://community.openstreetmap.org/t/improvements-in-thailand-reducing-the-risks-of-armchair-mapping/123857
